What is Entomology?

The OSU Department of Entomology invites you to explore, learn, study and research with us!Department of Entomology

Insects outnumber all other life forms combined. Although less than 5% are pests, they consume about 20% of the world's crops. Throughout history, insects have killed more people than war.  Fortunately, many more species of insects are beneficial, helping to control pests and recycle nutrients.  Without pollination by honey bees and other insects, our diet would have few fruits and vegetables. 

Fulfilling the Teaching, Research, and Extension Land Grant missions

OSU Department of Entomology is the only university department in Ohio focused on the study of insects

  • Using insects as model systems to further fundamental understanding of molecular biology, physiology, genetics, ecology, and evolution. 
  • Providing instruction at the Undergraduate (Major and Minor) and Graduate levels (M.S. and Ph.D).
  • Reaching out to our stakeholders with our Extension and Outreach programs to provide non-biased, research-based information to help protect crops, natural resources, structures, and human and animal health. 
Investigating the impact of insects
  • Pollination, biological control, and other beneficial services as well as contributing to environmental biodiversity
  • Sustainable production of our vitally important corn, soybean and wheat industries in Ohio;
  • Growing and emerging industries of fruit, vegetable, horticultural and specialty crop production, which increases the availability of nutritious foods and food security
  • Disease transmission and the health of animals and humans;
  • Healthy soils and agricultural production across urban and rural communities, and
  • Food systems and how these can be transformed for better resiliency and sustainability
